` In Germany December 11i, 1936 comme `linie-.Liray This invention relatesto' as` toy in the form of a "vehicle (motor car, locomotive, locomobile,`

tractor or `thelike) an aeroplane or aTstatoTiary engine, in any caser a large technical structure with audible engine, preferably internal combustionengine', and consists `chieily ine-that, by meansof a self-acting percussion mechanism, for

example actuated by the driving mechanism of i the toy, the sound of the engine of the large technical structure is imitated true to nature as regards ,kind and rhythm of thesoind. The percussion mechanism is `constructed and arranged so that itacts (at the same time/"as a speed regulation means for the driving mechanism.`

`l5 Anembodiment offthe invention `as applied to e atoy motor car is illustrated by way of example` in the accompanying drawing in `whichz` Fig. 1 shows the motor car in longitudinal section." i i, f Fig. 2 is atop plan view, the top casing being removed. I i l Fig. 3 is across section. i Figs. 4 and`5 show details.

The vehicle comprises a top casing a and aI bottom casing b enclosing 'the sound producing device. lA frame e carrying the spring motor rests on a base plate d mounted in a recess c in the casing. A pinion f of the spring motor is mounted on a shaft projecting through the frame e and provided at its ends with oppositely directed cranks g, y' on which upwardly bent at connecting rods h, h" arranged parallel to the longitudinal axis of the vehicle, are mounted. The percussion mechanism in the front part of the vehicle is connected to these rods and comprises the following parts:-

Two straps l, l' are rotatably mounted sidfby side on a stationary axle i and form arms n, 'n' carrying striker heads 0, 0'. The connecting 40 rods h, h are hingedly connected to the straps l and l at k. The arms n, n' may be rigid or resilient and, if desired, they may form separate parts onthe straps l, l'. The straps l, l' are mutually l displaced in the samesense as the cranks y, y. The striker heads 0,10 extend through'an aperture p in the base plate d and act `on a diaphragm q arranged below this plate d and mounted on a resonance board r. This resonance board which is curved like a sound box,

has a sound aperture s and is iitted in the casing of the toy in a suitable manner.

On one side of the driving mechanism frame. a

lever is mounted at t, one arm u of this lever being directed upwardly and so arranged that it can be actuated by hand, whereas the flat bent end o' ofthe other lever arm v is situated so that it can be brought within the range ofrnovement ""of the connecting rod h' near crank y'.

When the! spring motor is" operation and lever u, v assumes the position shownfin Figi-i; 5 the connecting rods h, h'," during the rotation of the pinion f, willbe reciprocated in counter sense by means of `the cranks g, yf and by means of these rods the straps l, `l will be rapidly oscila,

lated on the axle i. Consequently` the strikers 10 formedbyythe parts n and 0, o `alternately strike the diaphragm `q in `quick succession. Thus, `a percussion noise is `produced which is amplified by the resonance `board r and damped by the casing ab. This sound corresponds 15 `according to kind andrhythm with the noise made by the motor of a motor `vehicle which the toy simulates. i

The percussion mechanism l, n, o, l', n', o and the rods h, h' act on `the pinion flike a gov- 20 ernor. Thusthe whole `springmotor is inuenced in the same manner as by means of a speed regulator, so that a separate regulating device can be omitted which would otherwise be neces-` sary. i 25 The striking mechanism is renderedinop'era-` tive bymeans of a lever u, v; Fory this purpose the lever u is moved by hand in the direction of the arrow Fig. l and thereby the end v" of the lever arm v comes to bear against the connect- 30 ing rod h. By these means, the motor is also arrested.

The driven rear axle 2 of the vehicle may be disconnected from the driving mechanism independently of the striking mechanism. For this 35- purpose serves thedevice illustrated in Figs. 1, 2,54 and 5.

A pinion a: keyed on the rear. axle 2 meshes with a pinion y of the spring motor when the rear axle is engaged (Fig. 4). The axle 2 is slidably guided 40 in slots 3 in the motor frame e and mounted in a frame 5 pivotally mounted on an axle 4 within the motor frame e. A pin 1 on frame 5 projects through a slot 6 in the motor frame e and engages a lever 8 pivotally mounted at 9 on the outer side 45 of the motor frame e (Figs. 2, 4 and 5). The other arm l0 of this lever is upwardly directed and provided with a handle. By moving this lever 8, Ill the frame 5 is swung about the axle 4. The Wheel axle 2 participates in` the movement. 50 Thus, it is possible to stop the vehicle whilst the driving machine is still driving the percussion device. The sound of the motor, when the vehicle is standing still, is simulated and the toy enables the percussion mechanism to first be oper- `lili kun into the position shown in Fig. 5 and frame l swung upwards. The axle 2 swinging with the frame 5 shifts in the guide slots)V so that the` pinion :r moves out of mesh with'the pinion y, thereby disconnecting the axle 2 from the driving mechanism. The vehicle then stands still, whereas the percussion device can be set inoperation by means of the driving mechanism. so that the sound of the enginev is reproduced when the.vehicle is standing still. If the lever B IU is moved back. the axle 2 is again engaged by means offrame 5 and the vehicle starts to` travel, the percussion mechanism remaining operative. When the lever v is 'operated vtoarrest the connecting rod h', as described, the entire action of the toy is stopped, i. e. the percussion mechanism and the drive of axle 2 are stopped.

According `to the characteristic ofthe soundof the motor which is to be made audible, more than two strikers or only a` single Istriker may be employed. Furthermore, the percussion mechanism may be constructed in a different manner to that `shown in the drawing.

The invention can be applied to any toy which representsa large technical structure with driving or operating engine 'and audible machinery. Reproductions of large stationary machines come into question besides vehicles and aeroplanes.
